Steelfire

An unfortunate smith in Khoraja found himself homeless when his premises burned to the ground. Unable to explain the fire or its root cause, he nevertheless noticed that the steel he had been working on had survived the fire intact and was hardened beyond any metal that he had worked with before.Being a cautious man, he experimented with different variations of the equipment in his newly rebuilt smithy until he reached the conclusion that tar from his poorly sealed roof had dripped into his bloomery and tainted the brimstone that he was using as a catalyst.He gave his new catalyst the fanciful name of Steelfire and made a great deal of money before other smiths were able to replicate his results
